CAR-WHEEL.

To all whom z't may concern:

Be itl known that'we, VINCENT J. CoNoEs, Sr.,and VINCENTJ. CONCES, Jr., citizens of the United States, residing at East Chicago, in the county of Lake and State of Indiana,

have invented new and useful Improvements in Car-Wheels, of which the following is a specilication. c

- This invention relates to improvements in car wheels and has vparticular application to a wheel which is purposedly'designed for movably 'supporting cars used in foundries for moving molds, flasks, plates or *the like. Y

lIn foundry use after. the mold has been made, it isplaced in the car whereupon the car -is then moved into the oven for the4 purpose of drying the mold. When movingv 'the car into the oven the'mold is subjected.

to a heat of great intensity and consequently lthe car wheels. .In using the cars in the ordinary construction, in which the wheels are journaled upon the axles, the great heat to which the axles are subjected causes an` expansion of the frictional surfaces whereby the wheels are locked against rotation` structing a car wheel which eliminates the use of axles and furthermore obvlatmg the- 40 liability of'the wheels expanding to prevent the rotation thereof when subjected to the heat in the oven.

Another characteristic of this invention is to provide a device of the above described character in which the Wheels are provided with flanges 'that are engageable with the rails upon which the wheels are mounted to prevent-the accidental derailing of the car.

Another characteristic of this invention is to` provide a car wheel comprising a casing and a ball loosely mounted within the casing and engageable with the rails to movably support the car upon the rail, the casinfg beingformed in sections to permit the Specification of Letters Patent.

interchanging or the bau in the event that 1t becomes worn and distorted.

A further characteristic of this-invention resides in the provision of a device of the above described character which contains the desirable features of simplicity, dura'- bilit-y and` efficiency and furthermore a devle which may be manufactured at a nominal cost'.

Other characteristics of the invention will appear as the specification is read in connection with the accompanying drawing, "n which Figure 1 is a side elevation of our improved form of wheels showing the same applied to a car.

Fig. Q is a bottom plan view of one of the wheels.

Fig. 3 is a transverse section taken on the line 3 3 of Fig. 1.

Fig. 4 is a longitudinal section of Fig. 1.

Fig. 5 is a longitudinal section of a modi-f fled form of wheel.

Fig. 6 is a further modified form.

Fig. 7 shows a section of the preferred form of wheel.

Referring'to the drawings in detail, our invention 'comprises a car generally indicated as at A which is formed of the upper rectangular frame 1 and the lower rectangular frame 2. The frames 1 and 2 are disposed in spaced relation to each other and are connected by the side and end rails 3 and 4, at their confronting faces. Within this structure are longitudinally extending bars 5 preferably I-beams which are arranged at regular spaced intervals and have their opposite ends secured to the end rails, as is clearly shown in the drawings. Between the I-beams or bars 5 and side rails are the reinforcing blocks 7 and between the'barsare other blocks 8, all of which extend transversely o f the car and are arranged at various intervals throughout the which is of strong and durable construction and which minimizes the liability of the collapsing of the car when subjected to the intense heat of the foundry furnaces. It is to be understood that when using this car in foundries the mold is adapted to be placed upon the upper side of the car, the articu- ,.-lar arrangement of the blocks Slzan barsi preventing the sagging orl bending of the bars and producing a car which is highly desirable for the purpose for which it is intended.

Secured to the under side of the lower frame 2 at the opposite ends thereof and eX- tending transversely of the ear body are the 'plates 9 which are provided with the openings 10, the openings being adapted to receive the chains (not shown) for securely holding the mold upon the Car. Detachably secured to the under side of the plates 9 are our improved forms of wheels generally indicated as at B,the wheels being arranged upon the plates 9 in pairs, the wheels of one pair being arranged in longitudinal aline y ment with the wheels of the remaining pair to form a substantial support for the car A. The wheels B each comprise two sections 11 and 12, the upper section 11 being of substantially rectangular .formation and having the side walls thereof curved in the form of an arc to reinforce the construction thereof. Secured to the lower face of the upper section 11 is a lower section 12 which is of substantially semi-circular fori mation the side walls thereof being rounded to form a continuation of the rounded sides of the upper section 11, thus producing the curved sections which are strong and substantial. The curved or lower sides of the lower sections 12 are each provided with arcuate shaped grooves 13 which form the spaced flanges 14.

In the preferred embodiment of our invention as shown in Fig. 53 of the drawings, the lower section 12 is provided at'its medial portion with a vertically extending cylindrical bore or opening 15, the lower end of the opening being disposed within the grooves 13 and between the flanges 14. The upper'l end of the opening 15 hasvthe walls thereof interiorly threaded to receive the y plugs 16, the lower end of they plug being curved in the form of an arc to provide a bearing 17. Mounted within the lower end of the opening 15 is a ball 18 which is formed of any suitable material such as metal or the like and which is of a diameter slightly less than that ofthe opening 15 to permit free rotation .of the same therein. The lower end of the opening is restricted by a flange 1S) whereby a portion of the surface of the ball 1S will be disposed eX- teriorly of the section for contact with the rail as is clearly shown in the drawing. The bearing 17 is adapted to engage the ball 18 to prevent upward movement of the latter and at the same time to allow the ball 18 to freely rotate within the opening 15. By threadedly mounting the plug 16 within the opening 15, the same may be adjusted vertic-ally within the opening to allow for expansion and contraction of the ball 18 when the car is within the oven of the'furnace whereby the acoidentalbinding of the ball to prevent rotation thereof will be eliminated. It will be evident from the foregoing construction that when the Wheels B are placed upon the tracks, the balls 18 will rotate over the surface of the rail to permit the moving of the car thereupon, while the iianges 14 will be disposed upon the opposite sides of the rail to prevent excessive lateral movement of the car and consequent derailing of the same.

It will be thus seen that We eliminate the use of axles and the liability of the rotating element binding under the action of the intense heat when the car is in the oven of the furnace, and that the liability of the car becoming stalled within the open is eliminated. p

To originally hold the wheels within vertical position the plates' 9 are provided with brace bars 20 which extend longitudinally of the plates and have their confronting ends engaging the opposite sides of the wheels as is clearly shown in the drawings. The brace bars engage the wheels in such a manner as to permit the ready removal of the lower sections 12, it being understood that the lower sections are detachably connected with the upper sections 11 by means of the rods 21 and the bolts 22.

In Fig. 5 we have shown a modified form of wheel in which the lower section 12 is provided with a similar opening 15`which has its lower end restricted by the flange 19, the pair of balls 23 being mounted within the opening and having their surfaces engaging each other. The lower ball is adapted to project into the groove 13 while the upper ball is confined within the opening by means of the plate 24, the latter being formed`with an opening 25 which is of a diameter less than the opening 15 whereby the upper ballwill be locked in the opening 15 as will be understood.

' In Fig. 6 we have shown a further modiication in which a single ball is mounted within the opening 15, the opening 15 being of spherical formation 'to receive vra relatively large ball 26 which has av portion thereof disposed within the groove 13. The ball 26 is conined within the opening 15 by means of the plate 27 which is arranged upon the upper side of the section 12 and is provided at its medial portion with an opening 28 which is of a diameter less than that of the opening 15 whereby the accidental relmoval of the ball will be prevented. It is to be understood that the plate 27 is remov.

.ing

an improved construction'of car and wheels which is particularly useful in temperatures .of great intensity and especially 1n foundries for transporting molds to and fro from the oven of the furnaces. The proper operation of the car is insured in that the car body which is of a strong and substantial construction to prevent the accidental collapsing ofr the same and furthermore the wheels arevso constructed 'as to eliminate the liability of binding when the frictional surf 'faces are expanded.-

'l It is thought from the foregoing taken in conjunction with the accompanying'drawings, that the construction and operation of our device will be apparent to thoseskilled in the art, and that minor changes in the size, shape, proportion and minor details of construction may be made without departing from the spirit and scope of the appended claims.
